`Application filed April 16, 1915. Serial No. 21,813.

' '0 all Lv/0m it may concern Be it known that vl, H'. L. Hawks, a citinen of the United States, residing at F leming, in the county of Center and State of Pennsylvania, have in vented new and useful Improvements in Tool-Adjusters for Cultivators, of which the following is a specification.

ThisV invention relates to cultivators and especially to that class of cultivators which are used for the cultivation of garden truck.

Cultivators of this class usually include a wheel supported arch member and a plurality of tools adapted to be adjustably connected with and supported by said arch. A plurality of tools is desirable in order that the proper tools may be used for the many various kinds of crops that are raised and which require different treatment. It is also of great importance that means be provided for properly adjusting and supporting the tools for the various exigencies that may arise.

The present invention has for its object to provide a tool supporting device of simple and improved construction which is capable of being readily applied to and used in connection with a supporting arch of ordinary construction, said arch forming a part of a well known supporting frame; the construction being such that thetool carried by the improved supporting device will be capable of adjustment in` various angularly disposed planes, thus enabling the tool to be mounted in the most advantageous manner for the work to be performed.

A further object of the invention is to simplify and improve the construction and arrangement of the parts constituting the invention.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying drawing has been illustrated a simple and preferred form of the. invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that chan des, alterations and modifications within t e scope of the claim may be resorted to when desired.

In the drawing,-

Figure 1 is a perspective view of an arched axle equipped with the improved tool supports.

Fig. 2 is a top plan view of the Fig. 3 is an end view.`

Fig. 4 is a perspective view showing the members of the improved tool support separated from each other. V A A' Corresponding parts in the several figures are denoted by like characters of reference.

The improved tool support comprises a yoke 15, a. disk 16 abutting on the underside of the yoke and having downwardly extending arms 17 and a central perforation 1S; a bolt 19 extending through the perforation and having a non-circular head 20 positioned between the arms 17 g and a nut 21 and washer 22 engaging said bolt. The opposed faces of the yoke 15 and the disk 16 are preferably roughened, as indicated at 23, to present anti-slipping meeting faces. The lower extremities of the arms 17 may be connected together by a cross piece 17.

The arch, a specimen of which is shown at 24, is provided at the ends of its limbs with offsets 25 having apertures for the passage of bolts 26 whereby the yokes 15 are assembled with the arch, one yoke being connected with the offset 25 of each limb. The limbs of the arch are each provided with a forwardly extending arm 30 adapted for connection with the carrying frame of the implement to which the present invention constitutes an attachment.

The tools, a specimen of which isshown at 27, are each provided with a shank 28 apertured transversely for the passage of a bolt whereby the tool may he adjustably connected with the arms 17, the connecting bolt 29 being straddled by the arms.

It will be readily seen from the foregoing description taken in connection with the drawing that the yokes 15 are adjustable about the axes of the bolts 26, whereby they are connected with the arch. The disks 16 carrying the arms 17 are likewise adjustable about the axes of the bolts 19, the adjustment of the disks and the yokes being in substantially horizontal planes, enabling the distance between the tools carried by the two limbs of the arch to be varied, and also enabling the angular position of the tools to be varied about a substantially vertical axis. Adjustment of the tools may also be made same.

about the substantially horizontal axis of the bolts 26, thereby providing not only for the substantially universal adjustment of the tools, but for the various spacing thereof.

The improved adjusting device herein shown and described is not only Very durable and inexpensive, but the various adjustments may be effected with very slight expenditure of time, thus providing a device Which is thoroughly useful for the purposes indicated.

Having thus described the invention, what is claimed as new, is

In a device of the class described, a tool carrying element consisting of a disk having a central aperture and downwardly extending limbs at opposite sides of said aperture,

a bolt extending upwardly through the aperture and having a non-circular head nonrotatably engaged between the limbs, a longitudinally slotted plate through which the bolt extends, said plate and the disk having roughened opposed faces whereby the disk Will be securely retained at any longitudinal or axial adjustment, and a supporting element With which the longitudinally slotted plate is adjustably connected.

In testimony whereof l affix my signature in presence of two Witnesses.
